a long life , they will eventually approach the end of their service lives.
Our site; 2 storey bungalow does help us on our main topic which is “Nothing Is Considered A
Waste”. When we had our first visit, we didn’t tell the workers about our main topic but we asked
them about how’s the condition of the materials and how do they handling it. They straight away
Reasons: -
respond with , “ We are handling it very well and we try on not to waste most of the materials
1. Handling and stacking breakages
because the cost is quite expensive and it is part of their work’s etiquette”. We were quite surprised
2. Ordering mistakes
and amused with how they handling their work because the site can be considered quite clean and
3. Cut bricks (i.e. off-cut sand breakages are rarely reused)
neat through our vision. As we went for the second and so on visit, we can see there were still wastes
4. Use of bricks for scaffolding and other unintended uses
happening even though they arranged it well inside the big material bins.

In conclusion, we questioned ourselves; why must there still be a waste in construction site even

Wherever possible, waste reduction is the preferable option. If waste is produced, every effort

should be made to reuse it if practicable. Recycling is the third option in the waste management
hierarchy. Recycling does help to conserve resources and reduce wastes, it is important to
REFLECT TO
remember that there are economic and environmental costs associated with waste collection
This is the most materials that they really use it wisely and
try to prevent from wasting it because of the cost and
and recycling. For this reason, recycling should only be considered for waste which cannot be
pollution’s effect. That is why we could notice this material
reduced or reused. Finally, it may be possible to recover materials or energy from waste
which cannot be reduced, reused or recycled.
